Description

Technical Field

[0001] This utility model relates to the field of automotive water pump technology, specifically to an automotive water pump structure. Background Technology

[0002] Centrifugal water pumps are widely used in automobile engines. Their basic structure consists of a water pump housing, connecting disc or pulley, water pump shaft and bearings, water pump impeller, and water seal device, making them a major component of the automobile. Driven by a fan belt, they pump hot water out of the engine block's water passages and cold water in. Next to the water pump is a thermostat. When the car is cold, it doesn't open, allowing coolant to circulate only within the engine, a process known as the small circulation. Once the engine temperature reaches above 95 degrees Celsius, it opens, pumping the hot water into the radiator. The cool air from the moving car blows through the radiator, carrying away the heat.

[0003] A search of existing technologies reveals that CN115823010A discloses a novel automotive water pump sealing ring with high strength and easy installation. The car water pump housing has a retainer at its top, with an inlet pipe connected to the top of the retainer and an outlet pipe connected to the surface of the retainer. Both the inlet and outlet pipes have connecting sleeves at their other ends. A bearing is housed inside the car water pump housing, extending to the bottom of the housing. A pulley is fixedly mounted on the bottom of the bearing. An installation groove is formed at the top of the inlet pipe, containing a sealing ring body. A pressing plate is positioned at the top of the sealing ring body. The top of the inlet pipe extends into the connecting sleeve, where evenly distributed mounting plates are fixedly mounted on the inner wall. A ball bearing is positioned at the bottom of the mounting plates, abutting against the pressing plate. Receiving grooves are formed inside the inlet pipe on both sides of the bottom of the sealing ring body. A spring is fixedly mounted inside the receiving groove, with a jacking block fixedly mounted on the top of the spring. The jacking block is located at the bottom of the sealing ring body.

[0004] The comparative document uses a ball bearing to compress the extrusion plate, applying a uniform pressing force to the sealing ring body. This ensures the stability of the sealing ring body within the mounting groove and further improves its sealing performance. However, the high pressure inside the water pump flow channel and the uneven pressure on both sides of the sealing ring can lead to a decrease in sealing effectiveness after use. Utility Model Content

[0005] The purpose of this invention is to provide an automotive water pump structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a cover plate is provided, the surface of the cover plate is provided with a plurality of fixing holes, the lower surface of the cover plate is provided with a pump blade, the upper surface of the cover plate is provided with a motor chamber, a motor is fixedly connected in the motor chamber, the motor is connected to the pump blade, a fixing groove is provided on the lower surface of the cover plate, a plurality of fixing mechanisms are provided in the fixing groove, and a sealing ring is installed on the fixing mechanism.

[0007] Preferably, a fixing point is fixedly connected to the cover plate, the fixing point is perpendicular to the plane of the cover plate, a fixing hole is provided on the fixing point, and a reinforcing rib is fixedly connected to one side of the fixing point.

[0008] Preferably, a raised ring is fixedly connected to one side of the sealing ring, the raised ring is disposed in the middle of the side of the sealing ring, and the position of the raised ring is disposed on the side of the sealing ring closer to the center of the cover plate.

[0009] Preferably, the fixing mechanism includes a base plate, a sliding groove is provided inside the fixing groove, the base plate is slidably connected in the sliding groove, a vertical plate is fixedly connected to one side of the base plate, an inclined block is provided on the upper surface of the vertical plate, a limit block is slidably connected to the lower surface of the inclined block, an inclined surface is provided on the upper surface of the limit block, a positioning piece is provided on one side of the limit block, and the positioning piece is adapted to the protruding ring.

[0010] Preferably, the limiting block is provided with sliders on both sides, and the fixing groove is provided with a matching limiting groove inside.

[0011] Preferably, the shape of the fixing groove is the same as the outer edge shape of the cover plate.

[0012] Compared with existing technologies, the beneficial effects of this utility model are: the water pump sealing ring structure utilizes a raised ring anti-dislodgement and anti-tipping structural design. Simultaneously, multiple fixing mechanisms are set in the fixing groove to further secure the installed sealing ring, enhancing sealing performance. Furthermore, additional fixing points are added to the cover plate, simplifying the number of engine assembly components and reducing installation space. Two hard positioning mechanisms are integrated: one for the connection between the pump body and pump base, and the other for the connection between the side and front cover. When installing the sealing ring, place it in the fixing groove and then press it downwards. Pressing the sealing ring causes it to press against the base plate. This causes the base plate to move towards the inclined surface, allowing the positioning piece to move towards the sealing ring under the pressure of the inclined surface, thus contacting the raised ring of the sealing ring and limiting its movement to prevent it from dislodging.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4 The embodiments provided by this utility model are as follows:

[0020] Example: The device includes a cover plate 1 with multiple fixing holes 2 on its surface. A pump impeller 3 is located on the lower surface of the cover plate 1, and a motor chamber 4 is located on the upper surface of the cover plate 1. A motor 5 is fixedly connected to the motor chamber 4 and is connected to the pump impeller 3, enabling the motor 5 to drive the pump impeller 3 to rotate. A fixing groove 6 is formed on the lower surface of the cover plate 1, and multiple fixing mechanisms 7 are provided within the fixing groove 6. A sealing ring 8 is installed on each fixing mechanism 7, and the multiple fixing mechanisms 7 can fix and limit the sealing ring 8.

[0021] A fixing point 9 is fixedly connected to the cover plate 1. The fixing point 9 is perpendicular to the plane of the cover plate 1. A fixing hole 2 is provided on the fixing point 9. A reinforcing rib is fixedly connected to one side of the fixing point 9. The fixing hole 2 can increase the number of fixing points 9, improve the integration, and facilitate the installation of the cover plate 1.

[0022] A raised ring 10 is fixedly connected to one side of the sealing ring 8. The raised ring 10 is located in the middle of the side of the sealing ring 8, and its position is on the side of the sealing ring 8 closest to the center of the cover plate 1. The raised ring 10 can prevent it from falling out and tilting, thus improving stability.

[0023] The fixing mechanism 7 includes a base plate 12. A sliding groove 11 is formed inside the fixing groove 6, and the base plate 12 is slidably connected within the sliding groove 11. A vertical plate is fixedly connected to one side of the base plate 12. An inclined block 13 is provided on the upper surface of the vertical plate, and a limiting block 14 is slidably connected to the lower surface of the inclined block 13. An inclined surface is provided on the upper surface of the limiting block 14, and a positioning piece 15 is provided on one side of the limiting block 14. The positioning piece 15 is adapted to the protruding ring 10. After the sealing ring 8 presses against the base plate 12, the base plate 12 can move the inclined surface, thereby causing the inclined surface to drive the positioning piece 15 to press against the protruding ring 10, preventing the protruding ring 10 and the sealing strip from falling off.

[0024] The limiting block 14 is provided with sliders 16 on both sides, and the fixing groove 6 is provided with a matching limiting groove inside.

[0025] The shape of the fixing groove 6 is the same as the outer edge shape of the cover plate 1.

[0026] When it is necessary to install the sealing ring 8, place the sealing ring 8 in the fixing groove 6, and then press the sealing ring 8 downwards. Pressing the sealing ring 8 will cause the sealing ring 8 to press against the base plate 12. This will cause the base plate 12 to move the inclined surface, so that the positioning piece 15 moves towards the sealing ring 8 under the pressure of the inclined surface, thereby contacting the protruding ring 10 of the sealing ring 8 and limiting the sealing ring 8 to prevent it from falling out.
